Mensch, whose district includes parts of Bucks, Lehigh, Montgomery and Northampton counties, filed his appeal in Berks County Court last week. He was found guilty of summary disorderly conduct on May 9.

In court proceedings, a Berks County prosecutor said Mensch displayed a handgun as he and Brian Salisbury, 55, drove down I-78 in Berks County in March. Salisbury told authorities Mensch displayed the gun as they drove — a claim Mensch has denied.

Mensch, 65, said he was holding a cell phone, not a gun. Mensch said he had a gun in the vehicle and only picked it up after he stopped for gas and Salisbury stopped too.

Neither Mensch nor his attorney, Rich Wagner of Harrisburg, could be immediately reached for comment for this story.
